The Chimney

Eco Chimneys is an improved version of eco friendly industrial chimney that was developed to effectively overcome limitations in the brick, steel and conventional RCC chimneys. Eco Chimney is a factory manufactured Precast cement concrete Chimney customised for almost all kinds of smoke and heat emitting industries. Eco chimney is a patented product that has been declared as an invention under category ‘’An improved version of chimney suitable for industrial units’’ by the government of India. With extensive research, it has been developed to effectively control pollution and improve fuel efficiency.

Technology / Methodology involved in Industrial chimney manufacturing

Cylindrically shaped individual concrete moulds are placed on top of one another to form the Precast Industrial chimney structure. The concrete structure is held together by an external skeleton in the form of a steel tower. External support allows the chimney to be minimally reinforced with steel avoiding cracks and damages during heat retention. The conical base of the chimney is constructed using precast concrete blocks, allowing flexibility to customise the shape and height of the base, and also the number and size of flue gas ducts. After the conical base is cured and ready, the modular rings are stacked on top of one another to complete the chimney structure. The concrete structure is secured to the exoskeleton at regular intervals during the construction process. The completed chimney is then fitted with the required accesories, painted & ready for commissioning.

Viability of the Design (Benefits over steel / Conventional RCC Chimneys)

  1. The concrete structure is factory manufactured. Prefabrication facilitates customisation to individual requirements of tolerance to temperature and chemical compositions in emission. Pre fabrication also minimises variations in the final product by constant check on quality.
  2. As the chimney comprises of several individual concrete section, in case of damages, individual sections can be replaced irrespective of their position in the concrete chimney.
  3. EC can be altered & transpositioned to future prospects. The Chimney can be dismantled, shipped and re-erected at a different location.
  4. The steel tresle not only acts as an exoskeleton but is also a permanent scaffold for maintenance, repairs & alterations.
  5. The Chimney is light weight compared to conventional RCC Chimneys; it can be tucked into minimal space and requires a far smaller basement.
  6. EC takes only 1/10th of the time required to construct a similar sized conventional RCC chimney. The Pre fabricated concrete structure is transported to the site only when the site is ready for construction. This just in time logistics model ensures that precious space in the site is not taken up by the industrial chimney construction process.
  7. We make Constant improvements in the Product & its Design enabling customization of taller, more efficient chimneys for our clients.

Pollution control measures (Inbuilt):

We can provide inbuilt pollution control measures within the basement or the structure of the PCC chimney. The type of pollution control measures is determined by the nature of emission and the requirement of the client.The measures are as follows
  • In built wet scrubber
  • Gravity settling chamber
  • Wet bottom
  • Cyclonic filteration systems
  • Effuluent evaporation system
  • Heat recovery system

Annual Maintanance contract

We also undertake all kinds of Industrial chimney maintenance services for our customers. These services include Alterations, Repairs, Replacements, Painting, ASH/ SPM removal, Up gradations and general maintenance.
